Technoking of Beats, the DeFi-based NFT game, has integrated the Chainlink Verifiable Random Function (VRF) to randomly determine which Beats NFT a user receives when deciding to mint a new one. Only 3000 Beats NFTs can be minted into existence, and Chainlink VRF will ensure that all remaining Beats are fairly accessible to users using a completely random and tamper-proof distribution model.

Understanding Technoking of Beats

Technoking of Beats is an NFT x DeFi game designed to yield the highest gains for those who understand the rules. The total supply of Beats is permanently limited to 3000 NFTs. It is not possible to mint any further Beats, and the majority of Beats will be burnt as part of the gameplay dynamics.

Users can only obtain Beats through drawing, upgrading, or purchasing them on NFT marketplaces like OpenSea. Beats are a digital art collectible created by a group of 9 artists who span across Hong Kong, New York, Melbourne, London, Los Angeles, Shanghai, and Singapore. Our Beats NFTs are a collection of all the memories of the past year, recorded forever onto the Ethereum blockchain.

Anyone can draw a Beat here, which is minted and randomized using Chainlink VRF. A Beat’s minting price starts at 0.1 ETH and reaches a maximum price of 1 ETH, using bonding curve dynamics to reward early users with lower prices. You can also buy a pack of 10 beats, with packs starting at 0.5 ETH, offering users a 50% bulk-buying discount.

As part of the game, there are 15 kingdoms, and at most 300 Technokings. There are at most 20 Technokings for each kingdom. There are two ways to make it in the game:

  1. Attract citizens into the kingdom, and be rewarded 20% of all fees made through your referral link.
  2. Be the Technoking of your kingdom, and collect 50% of the fees from the Rewards Pool, which is made up of 20% of all fees.

There is only one way to become Technoking:

  1. Draw a Beat. Every draw will return a level 1 Beat
  2. Level up by merging a Beat of the same kingdom with a different level
  3. For example:
    a. Level 2 💎🤲 x Level 3 💎🤲 = Level 5 💎🤲
    b. Level 2 💎🤲 x Level 1 Simp = ❌❌❌
    c. Level 1 Simp x Level 1 Simp = Level 2 Simp 4
  4. Level 10 of any kingdom = Technoking 👑
  5. You will receive the 50% fees from the 20% Rewards Pool when you mint your Level 10 Technoking NFTUsing Chainlink VRF for Fair Draws

Technoking of Beats requires a tamper-proof and verifiable source of on-chain randomness to determine the outcome of Beats draws in a provably fair manner. However, it is incredibly challenging to access an unbiased source of verifiable randomness in blockchain environments. For instance, on-chain random number generator (RNG) solutions like blockhashes can be manipulated by blockchain miners, while off-chain RNG solutions are often opaque and require extreme trust in a centralized party.

To overcome this difficulty, we are integrating Chainlink’s Verifiable Randomness Function (VRF), a highly secure RNG solution that is purpose-built for smart contracts. Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof. The smart contract will only accept the random number input if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof.

Due to the strong security properties of Chainlink VRF, neither the users, oracles, nor Technoking of Beats developers are able to manipulate the distribution of Beats NFTs. Additionally, users receive an unprecedented level of transparency and integrity that each draw is resistant to any form of manipulation.

“By integrating Chainlink VRF for on-chain entropy, we ensure Beats NFTs are distributed in a tamper-proof and verifiably fair manner,” said the Technoking of Beats Team. “Chainlink VRF improves the integrity of our blockchain-based NFT game by ensuring all users have a fair opportunity to become a Technoking and earn their share of the rewards pool.”
